What happened

The episode as NWS PHI wrote it up.

Irene produced torrential downpour rains that resulted in major flooding and a number of record breaking crests on area rivers, tropical storm force wind gusts with record breaking outages for New Jersey utilities, one confirmed tornado and a three to five foot storm surge that caused moderate to severe tidal flooding with extensive beach erosion over the weekend of August 27th and 28th. Irene is expected to be the costliest natural disaster in the history of New Jersey. Approximately one million people were evacuated from the coast and low lying areas prone to inland flooding throughout the state of New Jersey including all of Cape May County. Irene also caused record breaking outages to utility customers as around one and a half million people lost power throughout the state. Power was not fully restored until September 5th. The widespread flooding resulted in the second highest crest (highest was with Hurricane Floyd in September 1999) on record for the Raritan Basin, but the highest crest on record for many other river basins including the Passaic. Moderate tidal flooding occurred along the tidal Delaware River and Delaware Bay and minor to moderate flooding occurred farther north along the Delaware River. Moderate to severe tidal flooding occurred along the Atlantic Coast and Raritan Bay There were six direct deaths associated with Irene, all drownings. The deaths occurred in Salem County, Mercer County (two), Ocean County (two) and Morris County. Preliminary damage estimates in the whole state of New Jersey were near one billion dollars to approximately 200,000 homes and businesses. The closure of the Atlantic City casinos (only the third time in history) for three days caused an estimated 45 million dollars in lost revenue. The combination of wind and flooding forced the closure of about 350 main roadways in the state including sections of Interstate 287, the Garden State Parkway and the New Jersey Turnpike. The flooding rains and winds damaged the corn, peach, pumpkin, tomato, pepper, cucumber, potato and squash crops and feared will damage the blueberry crop in 2012. Drug industry production fell the week of August 29th because of traveling problems. Free ice and water were distributed in locations with widespread power outages. The American Red Cross distributed over 1,000 clean-up kits and 100,000 meals and snacks.

Tropical storm force wind gusts overspread New Jersey during the late afternoon and evening of the 27th and persisted through the afternoon of the 28th. Peak wind gusts averaged around 50 mph inland and around 65 mph at the coast. The strongest winds associated with Irene occurred at two distinct times. The first surge occurred during bands of heavier rain during the evening of the 27th and early morning of the 28th. The second peak occurred during the afternoon of the 28th when skies were clearing and deeper mixing of the atmosphere brought stronger winds to the ground. Most of the inland peak wind gusts occurred at this time. The rain associated with Irene overspread New Jersey during the late morning on the 27th, fell at its heaviest during the evening of the 27th into the early morning of the 28th and ended during the early afternoon on the 28th. Event precipitation totals averaged 5 to 10 inches and caused widespread record breaking flooding. Many locations broke August's all time monthly rainfall records even before Irene arrived. Because the flash flooding and flooding blended into one, all flooding related Stormdata county entries were combined into one under flood events. The storm surge of 3 to 5 feet caused moderate to severe tidal flooding along the ocean side and moderate tidal flooding in Delaware Bay and tidal sections of the Delaware River. The tidal flooding was during the evening and overnight high tide on the 27th across southern New Jersey, Delaware Bay and the Delaware River, but with the morning high on the 28th in Northern New Jersey. The morning high tide coincided closer with the high tide cycle and caused most of the severe tidal flooding to occur there. Minor tidal flooding persisted in tidal sections of the Delaware River during the high tide cycles from the 29th through the 31st.

Governor Chris Christie declared a state of emergency on August 25th. New Jersey Transit rail, bus and light rail operations were suspended on the weekend of the 27th and 28th. Full transit service was not restored until Wednesday August 31st. In Cape May County, countywide mandatory evacuations were ordered on August 25th, and for residents the next day. Traffic on New Jersey State Route 55 south of Vineland, New Jersey Route 47 and New Jersey Route 347 were only allowed to head north leaving Cape May County.

All Atlantic County shore communities east of U.S. Route 9 including Atlantic City were placed under a voluntary evacuation at 8 p.m. August 25th and the following day a mandatory evacuation effective starting 6 a.m. EDT. All Atlantic City casinos were shut down as the city faced the first mandatory evacuation in history. About 1,500 National Guard troops had been deployed in the state to help with evacuations. In Ocean County, all of the barrier islands including Long Beach Island were under mandatory evacuation starting at 8 a.m. EDT on August 26th. To relieve evacuation traffic, toll operations were temporarily suspended on the Garden State Parkway south of the Raritan River and on the Atlantic City Expressway. The southbound lanes on the Garden State Parkway south of exit 98 were closed at 8 p.m. EDT on August 26th, while eastbound traffic was stopped on New Jersey State Routes 70 and Route 72.

Major flooding occurred on the Raritan, Millstone, Rockaway and Passaic Rivers. Record flows were reported at the Musconetcong River in Warren County as well as the Assunpink Creek in Mercer County and the Rancocas Creek in Burlington County. Flooding on the rivers lasted as long as September 5th. The flooding affected and closed numerous roads, including the heavily used Interstate 287 in Boonton when the northbound shoulder collapsed from the force of the Rockaway River. The Garden State Parkway flooded in Toms River near exit 98. On Monday August 29th, eighty roadways were still closed and thirty-six roadways were still closed on the 30th. Ninety-eight percent of the closed roadways were reopened as of September 1st. Coupled with a reduced transit schedule, travel was described as gridlock on the 29th Thousands of homes were also flooded, especially in Morris and Somerset Counties. Many northern New Jersey schools that were scheduled to open on the 29th were closed.

At the Trenton Train Station along Assunpink Creek, flooding impacted Amtrak's Northeast Corridor, SEPTA's Trenton Line, and New Jersey Transit's (NJT) Northeast Corridor Rail Line. Service was not fully restored to and through Trenton until August 31st. Irene cost NJT just under $10 million in lost revenue and damaged infrastructure. Numerous homes suffered structural damages from the winds, and limbs impacting their roofs.

In total, approximately 1.6 million customers of JCP&L and PSE&G throughout the state lost power. Two days after the storm, 500,000 PSE&G customers were still without power, down from a peak of about 928,000. By September 3 power had been restored to all but 750, but thousands of JCP&L customers were still without service. On September 2nd, 37,000 JCP&L customers were awaiting restoration of service. On Sunday September 5, power had been returned to last remaining 2,000 residents who suffered a power outage.

There was one confirmed tornado in Mercer County, but widespread tree wind damage (and damage to homes and vehicles when trees fell on them) occurred in every county. In addition, a few municipalities experienced stronger wind bursts that caused direct property damage. The strong winds forced the suspension of service on the Cape May Lewes Ferry. In Monmouth County, in Long Branch, the high winds damaged two roofs of an apartment complex on Ocean Boulevard. In Ocean County, an estimated 500 trees were knocked down. The SpongeBob ride at the Funtown Pier in Seaside Park was damaged. In Atlantic County, a piece of an exterior wall of the Borgota Hotel was blown off. In Gloucester County, a 61-year-old woman suffered a head injury after being struck by a tree.

The shore took a pounding from the coastal flooding and heavy surf. A 25-year-old and a 24-year-old man drowned in Point Pleasant (Ocean County) after going to the shore to view the storm. The average sand loss was about four to five feet high and one hundred fifty feet wide. Waves were estimated to reach as high as 12 feet as offshore seas reached 25 feet. There were numerous reports of dune fence damage and sand overwashes onto streets and boardwalks. Along the Raritan Bay side of Middlesex and Monmouth Counties, most of the vertical cuts were less than two feet and no breaches were reported. In Keansburg and Union Beach in Monmouth County low lying bayshore communities experienced tidal flooding. About 3,000 county residents were evacuated along Raritan Bay. Along the Atlantic Ocean side of Monmouth County, vertical cuts averaged 2 to 5 feet. In Spring Lake, about one and a half miles of the borough’s boardwalk was damaged and closed. In Ocean County, vertical cuts averaged 2 to 4 feet north of Barnegat Light and 4 to 6 feet south of Barnegat Light. A dune cut was reported in Harvey Cedars. Dune washovers occurred in Brant Beach. In Beach Haven, dune cuts reached 10 feet and the geotubes at Merrivale Avenue were overtopped. No flood damage to homes was reported. The entrance to the Holgate Natural Area was impassable as stone and rubble were exposed. In Atlantic County, vertical cuts averaged 1 to 4 feet, but reached 6 feet in Brigantine. In Cape May County, vertical cuts averaged 2 to 4 feet. A couple of horizontal dune cuts occurred in North Wildwood and the top cap of a timber bulkhead was knocked off. In Cape May City, a horizontal dune cut occurred on Poverty Beach. | |President Barack Obama initially declared the state a disaster area, making residents of Bergen, Essex, Morris, Passaic and Somerset Counties and made them eligible for federal aid. The declaration was later extended throughout the state.

The highest wind gusts recorded during Hurricane Irene were 75 mph at Cape May Ferry Terminal (Cape May County), 69 mph in Harvey Cedars (Ocean County), 69 mph in Tuckerton (Ocean County), 68 mph in Cape May Harbor (Cape May County), 66 mph at the Atlantic City Marina (Atlantic County), 66 mph in Ocean City (Cape May County), 65 mph in Point Pleasant (Ocean County), 58 mph in Atlantic City (Atlantic County), 58 mph in Sandy Hook (Monmouth County), 58 mph in Brick (Ocean County), 57 mph in Keansburg (Monmouth County), 55 mph in Barnegat Light (Ocean County), 55 mph at Lakehurst NAS (Ocean County), 55 mph at Point Point (Atlantic County), 55 mph in Seaside Heights (Ocean County), 53 mph at Wildwood (Cape May County), 52 mph in Belmar (Monmouth County), 52 mph in Bivalve (Cumberland County), 52 mph in Trenton (Mercer County), 51 mph at Ft Dix-Wrightstown (Burlington County), 50 mph in Wantage (Sussex County), 47 mph in Mount Holly (Burlington County) and 42 mph in Somerville (Somerset County).

Peak storm tides included 9.75 feet above mean lower low water in Sandy Hook (Monmouth County). Severe tidal flooding starts at 8.7 feet above mean lower low water. This was the third highest tide on record and highest tide since the December 1992 nor'easter. Other peak tides included 6.96 feet above mean lower low water in Atlantic City (Atlantic County), moderate tidal flooding starts at 7.0 feet above mean lower low water; 8.55 feet above mean lower low water in Cape May (Cape May County), severe tidal flooding starts at 8.7 feet above mean lower low water; 8.03 feet above mean lower low water at Reedy Island, New Castle County Delaware, moderate tidal flooding starts at 7.2 feet above mean lower low water and 9.89 feet above mean lower low water in Philadelphia Pennsylvania, moderate tidal flooding starts at 9.2 feet above mean lower low water. Along tidal sections of the Delaware River, Big Timber Creek flooded along the Gloucester and Camden County lines and about 300 homes in Burlington City (Burlington County) had flooded basements.

Hurricane Irene formed east of the Leeward Islands on Saturday the 20th. It moved northeast and passed over Puerto Rico overnight on the 21st. As Irene moved off the island, it intensified into a hurricane. Irene just bypassed the island of Hispaniola to its north and then passed over the Eastern Bahamas on the 25th as it reached category three hurricane strength. From the Bahamas, Irene moved nearly due north and slowly weakened to a category two hurricane on the 26th and a category one hurricane on the 27th. Irene made her initial landfall near Cape Lookout, North Carolina at 8 a.m. EDT on the 27th as a category one and then proceeded to the northnortheast. Irene went back over the Atlantic Ocean near the Virginia and North Carolina border at 7 p.m. EDT on the 27th. From there Irene paralleled the Delmarva Peninsula and the center passed about 15 miles east of Delaware between 3 a.m. and 4 a.m. EDT on the 28th. Irene continued to slowly weaken and made her second landfall as a tropical storm on Brigantine Island, just north of Atlantic City, New Jersey at 535 a.m. EDT on the 28th. From there the center of Irene moved along eastern parts of Ocean and Monmouth Counties and was located near Tinton Falls Township in Monmouth County at 8 a.m. EDT on the 28th. At about 9 a.m. EDT the center of Irene passed over New York City.

Irene helped make August 2011 the wettest August on record for the state of New Jersey dating back to 1895. A new August monthly rainfall record of 16.10 inches was established in Trenton.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MOUNT HOLLY NJ
119 PM EDT SAT AUG 27 2011

.SYNOPSIS...
HURRICANE IRENE WILL IMPACT OUR REGION OVER THE WEEKEND. AS THE
REMNANTS OF THE SYSTEM MOVE UP INTO EASTERN CANADA ON MONDAY, HIGH
PRESSURE FROM THE WEST SHOULD BEGIN TO BUILD INTO EASTERN
PENNSYLVANIA, NORTHEASTERN MARYLAND, DELAWARE AND NEW JERSEY. THE
HIGH IS FORECAST TO INFLUENCE OUR REGION FOR MUCH OF THE NEW WEEK.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
**SIGNIFICANT TO DAMAGING AFFECTS FROM HURRICANE IRENE ACROSS THE
REGION ESPECIALLY LATER TODAY THROUGH ABOUT MIDDAY SUNDAY.**

IRENE HAD MOVED INLAND JUST WEST OF CAPE HATTERAS EARLY THIS
AFTERNOON, AND SOME WEAKENING WAS OCCURRING AS A RESULT, BUT THE
HURRICANE CENTER BELIEVES THE STORM WILL REMAIN NEAR HURRICANE
STRENGTH AS IT APPROACHES OUR AREA.

THE FIRST MAJOR RAIN BAND HAD MOVED ONSHORE TO OR NEAR THE
INTERSTATE 95 CORRIDOR. WE CONTINUE TO SEE OCCASIONAL SMALL SCALE
CIRCULATIONS IN THE LOWER LEVELS MOVING ONTO THE COAST, MOST
RECENTLY OVER COASTAL DELAWARE. A FEW QUICK HITTING TORNADOES THAT
DISSIPATE AS THEY MOVE INLAND ARE LIKELY.

WE CONTINUE TO WORRY ABOUT A COASTAL FRONT THAT HAD LOOKED LIKE IT
RETREATED SOME INTO THE SOUTHERN POCONO REGION EARLY THIS
AFTERNOON. WE BELIEVE THIS FEATURE CAN INTERACT WITH IRENE AND
ULTIMATELY ENHANCE HEAVY RAIN IN THE EVENT THAT THE SYSTEM BEGINS
THE TRANSITION FROM TROPICAL TO EXTRATROPICAL PRIOR TO ARRIVAL AT
THIS LATITUDE. FOR WHAT IT IS WORTH, THE LATEST AVAILABLE MAJOR
MODELS SEEM TO BE FORECASTING 3 TO 8 INCHES FOR OUR AREA. THE
LATEST GUIDANCE FROM OUR COLLEAGUES AT THE NATIONAL CENTER
FORECASTS 5 TO 9 INCHES OVER OUR AREA. GIVEN OUR CONCERN ABOUT A
SYSTEM TRANSITIONING TO EXTRATROPICAL WITH COPIOUS TROPICAL
MOISTURE, WE WILL BE MAINTAINING OUR 6 TO 10.

WE WOULD LIKE TO CONTINUE TO STRESS THAT IT IS IMPORTANT TO NOT
FOCUS ON THE EXACT CENTER AND DETERMINISTIC TRACK OF THE
HURRICANE, ESPECIALLY SINCE THIS PARTICULAR STORM IS A VERY LARGE
SYSTEM. WE EXPECT WIDESPREAD IMPACTS FROM THIS HURRICANE ACROSS
THE CWA.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH SUNDAY NIGHT/...
MOST OF THIS TIME FRAME WILL BE DOMINATED BY HURRICANE IRENE AS IT
MOVES VERY NEAR OUR COAST SUNDAY MORNING. THE WORST CONDITIONS
WILL BE TONIGHT AND SUNDAY MORNING. THERE IS A HIGH RISK OF AREAS
OF DAMAGING WINDS AND HEAVY/POSSIBLY RECORD SETTING RAINFALL
THROUGH SUNDAY MORNING.

OUR WIND FORECAST IS BASED OFF OF THE GRIDDED WIND FIELD FROM THE
OFFICIAL NHC FORECAST AND THIS WILL BE UPDATED WITH SUBSEQUENT
ADVISORY ISSUANCES. WE GENERALLY BASED OUR POPS MORE TOWARD A BLEND
WHICH ENDS UP SIMILAR TO THE GFS. INTERESTINGLY ENOUGH, THE WATER
VAPOR EARLY THIS MORNING SHOWS A MID LEVEL TROUGH CRUISING THROUGH
THE GREAT LAKES REGION. THE FLOW STRENGTHENING AHEAD OF THIS CAN BE
SEEN BY THE OUTFLOW FROM HURRICANE IRENE EXPANDING IN SIZE AND
NORTHWARD. THIS SHORT WAVE TROUGH APPEARS TO BE MOVING RATHER
QUICKLY EASTWARD, WHICH MAY END UP NUDGING IRENE A BIT FARTHER TO
THE EAST. A LOT OF THE MODEL GUIDANCE INDICATES THE STRONGEST
BOUNDARY LAYER WINDS STAY NEAR THE COAST AND THEN OVER THE OCEAN,
WITH FRICTIONAL EFFECTS REDUCING THE SURFACE WINDS INLAND. BASED ON
THIS, THE WESTERN PART OF THE HURRICANE WARNING INCLUDING
PHILADELPHIA MAY NOT QUITE MAKE IT WITH WINDS MOSTLY IN THE TROPICAL
STORM FORCE RANGE. GIVEN THE LARGE WIND FIELD, WE WILL NOT CHANGE
THESE ATTM. OVERALL, THERE CONTINUES TO BE A HIGH RISK OF IMPACTS
WITH THIS HURRICANE, WHICH INCLUDES DAMAGING WINDS, TORRENTIAL
RAIN, COASTAL FLOODING, DANGEROUS RIP CURRENTS, AND BATTERING
WAVES AND BEACH EROSION.

MUCH OF THE MODEL GUIDANCE STILL SHOWS THE DEVELOPMENT OF A STRONG
250 MB JET NORTH OF THE HURRICANE INTO SUNDAY, GENERALLY FROM THE
EASTERN GREAT LAKES TO NORTHERN NEW ENGLAND. THIS UPPER-LEVEL JET
EVEN HAS SOME ANTICYCLONIC CURVATURE TO IT AND GIVEN THE ORIENTATION
OF THIS JET IT IS SUCH THAT IRENE IS WITHIN THE RIGHT ENTRANCE
REGION AS SHE TRACKS NORTHWARD. THIS SCENARIO MAY TEND TO HELP WITH
A POLEWARD UPPER-LEVEL OUTFLOW CHANNEL AND ASSIST IN THE INTENSITY
OF THE SYSTEM AS A WHOLE. THEREFORE, DESPITE SOME INCREASING SHEAR
AS THE HURRICANE GAINES LATITUDE ALONG WITH COOLER WATERS AND LAND
INTERACTIONS, PERHAPS THIS IS WHY MUCH OF THE MODEL GUIDANCE NEARLY
INSISTS THIS SYSTEM MAINTAINS A RATHER LOW CENTRAL PRESSURE ALL THE
WAY INTO SOUTHERN NEW ENGLAND. IT BECOMES EVEN MORE OF AN INTENSITY
FORECAST CHALLENGE AS TROPICAL CYCLONES GET THIS FAR NORTH AND
INTERACT WITH BAROCLINIC ZONES AND LARGE SCALE SYNOPTIC FEATURES.
THE PRESENCE OF THE SURFACE FRONT AND UPPER-LEVEL JET IS CONCERNING
AS THIS MAY PLAY A SIGNIFICANT ROLE IN ENHANCING THE RAINFALL RATES.
THE AMOUNT OF RAIN THAT LOOKS TO OCCUR WITH THIS SYSTEM MAY END UP
BEING THE MAIN TOPIC OF DISCUSSION FOR MANY YEARS. AN EXAMINATION
OF THE WIND FIELD AT 925 MB IS STILL CONCERNING WITH A LARGE AREA OF
60 TO NEARLY 85 KNOTS TRACKING ACROSS THE CWA THIS EVENING THROUGH
SUNDAY MORNING. WHILE THE FRICTIONAL EFFECTS WILL TEND TO SLOW THE
WIND DOWN SOME AND ALSO ALLOW FOR SOME DECOUPLING BETWEEN THE
SURFACE AND ABOVE, THE PRESSURE GRADIENT COMBINED WITH ENHANCED
MIXING WITHIN HEAVIER RAIN/CONVECTION SHOULD PRODUCE
SIGNIFICANT/DAMAGING GUSTS.

ONE THING NOTED IS THE MODEL FORECASTS INDICATING A RATHER
IMPRESSIVE 3-HOUR PRESSURE RISE BEHIND THE HURRICANE SUNDAY
AFTERNOON. SOME FORECAST SOUNDINGS INDICATE THE POTENTIAL FOR AN
INCREASED THREAT OF DAMAGING GUSTS TO OCCUR AS THIS FEATURE MOVES
THROUGH AND VERTICAL MIXING SHARPLY INCREASES DUE TO SOME
CLEARING. IF THIS WERE TO PAN OUT, THE WINDS COULD BE STRONGEST
WHEN THIS SHARP PRESSURE FALL/RISE COUPLET MOVES THROUGH. WE
CONTINUE TO USE A 125 PERCENT OF THE SUSTAINED WINDS TO DERIVE OUR
GUSTS BUT NOW CAPPED THEM AT 75 KNOTS /20 PERCENT REDUCTION OF THE
SUSTAINED WINDS OVER LAND/. THE WIND GUST TOOL THAT INCLUDES
MIXING MAY BE TO HIGH ESPECIALLY OVER AREAS FARTHER INLAND. IT
APPEARS THAT THE HURRICANE WILL SPEED UP SOME, AND THIS FORWARD
MOTION COULD BE A BIT MORE IF THE INCOMING SHORT WAVE TROUGH IS
ENOUGH TO PICK IT UP QUICKER. WE THEREFORE CONTINUED THE TREND IN
QUICKLY TAPERING POPS DOWN SUNDAY AFTERNOON FROM SOUTH TO NORTH.

ONCE THE STORM MOVES OFF TO THE NORTH AND NORTHEAST LATER SUNDAY,
THE CONDITIONS WILL QUICKLY IMPROVE.

&&

.LONG TERM /MONDAY THROUGH FRIDAY/...
OVERALL A MUCH CALMER TIME PERIOD MONDAY THROUGH FRIDAY AS THE WIND
WILL QUICKLY DIMINISH MONDAY AS HIGH PRESSURE BEGINS TO BUILD IN. A
WEAK TROUGH WILL SKIRT OUR REGION TUESDAY, WHICH MAY INCREASE CLOUDS
A BIT. HIGH PRESSURE THEN BUILDS ACROSS ON WEDNESDAY BEFORE SLIPPING
TO THE EAST THURSDAY.

&&

.AVIATION /18Z SATURDAY THROUGH THURSDAY/...
THE FOLLOWING DISCUSSION IS FOR KPHL, KPNE, KTTN, KABE, KRDG, KILG,
KMIV, KACY AND SURROUNDING AREAS.

RAIN WITH EMBEDDED HEAVIER SHOWERS AND ISOLATED TSTMS WILL ADVANCE
FROM THE SOUTHEAST DURING THE COURSE OF THE DAY TODAY. THIS IS
EXPECTED TO TRANSITION TO A WIND DRIVEN RAIN THIS EVENING WITH THE
WORST CONDITIONS EXPECTED LATER TONIGHT AND SUNDAY MORNING.
THEREFORE, WE INDICATED CONDITIONS EVERYWHERE AT SUB-VFR WITH
PERIODS OF HEAVY RAIN. WHILE SOME THUNDERSTORMS SHOULD BE EMBEDDED
IN THE RAIN SHIELD, WE OPTED TO NOT INCLUDE IT AT THIS TIME GIVEN
LOW CONFIDENCE ON TIMING AND COVERAGE. ANY HEAVIER RAIN AND
THUNDER WILL HAVE THE POTENTIAL TO PRODUCE STRONGER SURFACE GUSTS.
OTHERWISE, WE GRADUALLY INCREASED THE WINDS THIS AFTERNOON AND
ESPECIALLY TONIGHT. WE WENT CONSERVATIVE WITH THE GUSTS AS IT IS
NOT COMPLETELY CLEAR HOW MUCH TRANSFER OF THE WINDS TO THE SURFACE
FROM ALOFT OCCURS. WE CARRIED THE STRONGEST WINDS AT KMIV AND KACY
AT THIS POINT. THERE COULD BE A SECONDARY SURGE OF RATHER STRONG
WINDS FOR A FEW HOURS SUNDAY AFTERNOON AS THE CENTER OF THE STORM
MOVES THROUGH AND A SHARP PRESSURE RISE OCCURS. THE WINDS WILL BE
SOUTHEAST TO EAST THEN SHIFT TO THE NORTHEAST THROUGH TONIGHT.

OUTLOOK...
HIGH PRESSURE WILL LIKELY INFLUENCE OUR REGION FROM MONDAY THROUGH
WEDNESDAY, WITH DRY WEATHER AND MAINLY VFR CONDITIONS. HOWEVER, SOME
LATE NIGHT AND EARLY MORNING VISIBILITY RESTRICTIONS ARE POSSIBLE
EACH DAY.

&&

.MARINE...
A HURRICANE WARNING REMAINS IN EFFECT FOR ALL ZONES. THE ARRIVAL OF
THE HURRICANE WILL GENERATE INCREASING WINDS FROM THE EAST AND
NORTHEAST. THE TRACK APPEARS TO TAKE THE CENTER OF THE STORM OVER OR
VERY NEAR OUR COASTAL WATERS AFTER MIDNIGHT TONIGHT. THIS IS A
LARGE SYSTEM THEREFORE THE WIND FIELD IS RATHER EXTENSIVE. THE
SIZE OF THIS SYSTEM IS ALSO AIDING IN A LARGE FIELD OF HIGH SEAS.
THESE SEAS WILL CONTINUE TO BUILD TODAY AND PEAK LATE TONIGHT AND
SUNDAY MORNING AS THE CENTER MOVES ON BY. THERE COULD BE A
SECONDARY SURGE OF WINDS FOR A FEW HOURS SUNDAY AFTERNOON AS
IMPRESSIVE 3-HOUR PRESSURE RISES MOVE THROUGH. WE GENERALLY
FOLLOWED WAVEWATCH FAIRLY CLOSELY BUT LEANED CLOSER TO CONTINUITY
REGARDING THE SUBSIDING OF THE SEAS LATE SUNDAY INTO MONDAY. AS OF
NOW, WE HAVE SEAS PEAKING BETWEEN 20-25 FEET.

THE CONDITIONS ARE EXPECTED TO IMPROVE SUNDAY NIGHT INTO MONDAY AS
THE SYSTEM MOVES WELL TO OUR NORTH AND THE PRESSURE GRADIENT EASES
SIGNIFICANTLY. THE OFFSHORE WINDS IN THE WAKE OF IRENE SHOULD ALLOW
THE SEAS TO SUBSIDE FAIRLY QUICKLY OVERALL.

OUTLOOK...
HIGH PRESSURE WILL LIKELY INFLUENCE THE COASTAL WATERS OF NEW JERSEY
AND DELAWARE FROM MONDAY THROUGH WEDNESDAY. WIND SPEEDS ARE FORECAST
TO STAY GENERALLY LESS THAN 15 KNOTS. WAVE HEIGHTS ON OUR OCEAN
WATERS SHOULD REMAIN HIGH ON MONDAY IN THE WAKE OF HURRICANE IRENE.
WAVE HEIGHTS ARE EXPECTED TO SUBSIDE SLOWLY ON TUESDAY AND WEDNESDAY.

&&

.HYDROLOGY...
HEAVY AND POSSIBLY RECORD SETTING RAINFALL TODAY AND SUNDAY MAY
RESULT IN MAJOR FLOODING ACROSS THE AREA.

THE PW VALUES FORECAST ACROSS THE REGION ARE RATHER IMPRESSIVE
WITH 2.0-2.5 INCHES OVERSPREADING THE REGION TODAY INTO SUNDAY.
IF THE CENTER GETS CLOSE ENOUGH TO THE COAST, SOME GUIDANCE
INDICATES THE PW VALUES INCREASE TO JUST OVER 3.0 INCHES. THIS
AMOUNT OF MOISTURE IN THE ATMOSPHERE WILL LEAD TO EXCESSIVE
RAINFALL RATES AND TOTALS. THIS COMBINED WITH ANY UPSLOPE
ENHANCEMENT AND/OR LOCALLY ENHANCED CONVERGENCE/BANDING WILL ADD
TO THE RAIN RATES. THE INITIAL INFLUX OF THIS HIGHER MOISTURE
CONTENT AIR ALONG WITH THE PRESENCE OF A STATIONARY FRONT WILL LEAD
TO BOUTS OF LOCALLY VERY HEAVY DOWNPOURS WELL BEFORE THE HURRICANE
GETS TO OUR LATITUDE.

SMALLER CREEKS AND STREAMS WILL BE HIGHLY SUSCEPTIBLE TO RAPID
FLOODING. THE RARITAN AND SCHUYLKILL RIVERS HAVE THE POTENTIAL TO
REACT RATHER QUICKLY AND ALSO ARE HIGHLY SUSCEPTIBLE TO FLOODING.
THE DELAWARE, SUSQUEHANNA, RANCOCAS AND PASSAIC RIVERS REACT MORE
SLOWLY, BUT THEY ALSO ARE HIGHLY SUSCEPTIBLE TO FLOODING. IN
ADDITION, THE WINDSWEPT RAIN WILL LIKELY PRODUCE URBAN AND POOR
DRAINAGE FLOODING. THE STRONG ONSHORE FLOW COMBINED WITH THE TIDES
WILL TEND TO BACK WATER UP, COMPLICATING FLOODING PROBLEMS. GIVEN
THE QPF FORECAST /6 TO 10 INCHES WITH LOCALLY UP TO 12 INCHES/ AND
THE ANTECEDENT CONDITIONS, THE FLOOD WATCH REMAINS IN EFFECT AND
WE CONTINUE TO CARRY A HEAVY RAIN MENTION IN THE FORECAST.

&&

.TIDES/COASTAL FLOODING...
THE THREAT OF MODERATE TO SEVERE COASTAL FLOODING REMAINS HIGH OVER
THE WEEKEND AS HURRICANE IRENE IMPACTS OUR REGION. THE SUNDAY
MORNING HIGH TIDE ALONG THE OCEANFRONT RARITAN BAY AND DELAWARE
BAY IS OF MOST CONCERN. HOWEVER, WITH THE STRENGTH OF THE STORM,
COASTAL FLOODING MAY VERY WELL BE AN ISSUE FOR HOURS BEFORE AND
AFTER THE HIGH TIDE OCCURS.

WITH WATER EXPECTED TO BE PUSHED UP DELAWARE BAY, FLOODING IS ALSO A
CONCERN FOR THE TIDAL PORTION OF THE DELAWARE RIVER.

COASTAL FLOODING ISSUES MAY LINGER INTO THE SUNDAY EVENING HIGH
TIDE, ESPECIALLY ALONG THE NORTHERN PART OF THE NEW JERSEY COAST AND
ALONG RARITAN BAY.

A CAVEAT TO THIS IS THE THREAT OVER THE NORTHERN CHESAPEAKE BAY.
IT DOES NOT APPEAR THAT WE WILL SEE MINOR TIDAL FLOODING WITH THE
AFTERNOON/EVENING HIGH TIDE TODAY, AND WINDS MAY SHIFT TO
NORTHWEST PRIOR TO THE OVERNIGHT HIGH TIDE. THE GREATEST THREAT TO
OUR PORTION OF THE MARYLAND EASTERN SHORE WOULD BE SOUTH AT TALBOT
AND CAROLINE COUNTIES, WHERE PERHAPS MODERATE TIDAL FLOODING STILL
WILL OCCUR.

&&

.RIP CURRENTS...
DANGEROUS RIP CURRENTS ASSOCIATED WITH HURRICANE IRENE ARE
ANTICIPATED THROUGH THE ENTIRE WEEKEND.

.EQUIPMENT...
TECHNICIANS CONTINUE TO WORK STEADILY ON THE FORT DIX, NEW JERSEY
